LEAN MODE DURING IDLING FOR REDUCTION OF THE NUMBER OF PARTICLES

摘要

The invention relates to an operating method for an apparatus (V), having an internal combustion engine which can be operated in a lean mode and a stoichiometric mode, a crankcase (1), at least one combustion chamber (4) and preferably a throttle element (11) via which charge air can be fed from a charge air cooler to the combustion chamber (4), wherein the internal combustion engine is switched to a lean mode during idling and is operated in the lean mode, with the result that, in particular, the pressure difference between the crankcase (1) and the combustion chamber (4) is reduced.
